What's your budget? If you need a cheap, powerful laptop, I'd go with the MSI GT60. It's $600 less than the Razer, but at least 15% more powerful. You can also change the graphics card. If you need a laptop that outperforms anything else on the market, I recommend the Alienware 18 laptop. Be warned: it's expensive. You can also use SLI with it. It's more like a small desktop, though, because it has only a few hours of battery life.
